This checklist compiles the most consistently cited warning signs from the CDC, NIMH, AFSP, and WHO. Any single sign doesn’t confirm risk, but the more that appear—especially together—the higher the concern. If several items are present, seek professional help immediately (call or text 988 in the U.S., or use your local crisis line).

• Saying ‘goodbye’ or giving final messages

2. Behavioral & Observable Actions
